摘要

摘要: 巨量的地铁工程余泥渣土在处置过程中会产生严重的环境影响。准确量化地铁工程余泥渣土的环境影响是对其进行有效管理的前提。为此,首先构建了地铁工程余泥渣土填埋占地量估算方法。其次,基于实地调研、半结构化访谈及文献综述,构建了地铁工程余泥渣土全生命周期碳排放评估方法。最后,以深圳地铁14号线为例,量化了余泥渣土的填埋占地量及其全生命周期碳排放。结果表明:深圳地铁14号线余泥渣土填埋处置的土地占用面积约为163.4万m²,将会产生4085万元的填埋费用;深圳地铁14号线余泥渣土全生命周期的CO₂排放量约为1.8E+07 kgCO₂eq。该研究结果可为政府部门科学制定地铁工程余泥渣土的管理政策提供理论方法及数据参考。

Abstract: A large amount of residual mud from subway engineering will have serious environmental impacts in the process of disposal. Accurately quantifying the environmental impacts of residual mud from subway engineering is the premise of effective management. In this study, firstly, the estimation method of the amount of land occupied by the residual mud landfill of the subway project was established. Secondly, based on field investigation, semi-structured interview and literature review, the life cycle carbon emission assessment method of residual mud from subway engineering was constructed. Finally, taking Shenzhen Metro Line 14 as an example, the amount of land occupied by landfill and its carbon emission in the whole life cycle were quantified. The results showed that: the land occupation area for landfill disposal of residual mud from Shenzhen Metro Line 14 was about 1.634 million m², which would generate a landfill cost of 40.85 million yuan; the total life cycle CO₂ emission of residual mud from Shenzhen metro line 14 was about 1.8 E+07 kgCO₂eq. The research results can provide a theoretical model and data reference for the government to scientifically formulate the management policy of the residual mud from subway engineering.
